I think another vet will be added. How valuable of one just depends on the market.Sure they will bring in more WR's (through the draft, no FA) but I'm still not seeing this as some death blow.
As for Baker improving I'd say two things. A he was really hurt last year and B I'd ask people to remember re-examine Dak's passing production before Amair arrived.
Personally I found this move as status quo for Amari.
